  <div>
   <p>This section describes how to live mount a copy of a VM to the original location or a new location to quickly start a new VM.</p>
   <div class="section">
    <h4 class="sectiontitle">Context</h4>
    <p>Live mount can be performed using backup copies or replication copies. Data can be restored to the original or a new location. Note that replication copies cannot be used to restore data to the original location.</p>
   </div>

You are advised to set only <strong>Bandwidth (MB/s)</strong> for bandwidth-intensive services and only <strong>Normalized IOPS (8 KB)</strong> for IOPS-intensive services. If you cannot determine the service type or the service type changes frequently, you can set both indicators and the system will control the traffic using the indicator with a smaller value.</li>
